[sf-lug] new computer

As Christian says, it make a considerable difference what specialty if
any you intend to tailor this thing for. However, this comes across as
a gamer box, nei?
> SAMSUNG 20X DVD±R DVD Burner Black SATA Model SH-S203B - OEM
SATA ATAPI support (CD, DVD, tape, and similar drives) was added in
Linux kernel 2.6.14. So, if you intend to use the above drive in your
distro's installer, you'll need to make sure the installation kernel is
version 2.6.14 or above. (That's pretty recent.)

I honestly doubt you can _buy_ anything smaller, any more. Time's
winged arrow moves on....

Dunno. Add up estimates for your big-ticket amperage draws, to hit the
ballpark. If in doubt, go for slightly heftier.
Note: Dodgy or overstressed power supplies are the second most fearsome
killer of electronic components, right behind heat buildup -- and I tend
to assume that offbrand PSU (power supply unit) manufacturers are lying
when they imply reliable delivery of X watts. A PSU that's trying to
deliver a bit more than it's capable of will very often go unstable and
kill all your attached hard drives, and possibly other things.
Me, I'd go with a really known-good brand that I _know_ really is 550W
of reliable power long before I'd go with some unfamiliar brand that
promises 650: Antec, Cooler Master, PC Power & Cooling. There are
probably other reliable brands, but those three are the ones that come
to mind (and are the ones I'd pay extra for).
I see that Central Computer sells Seasonic. That might make them a good
risk, but I've personally not heard of them before.

Not known -- but the model KW-21 CS works:

You're a man of good taste in RAM, sir!

> Motherboard
Northbridge: Nvidia Nforce 680i SLI
Southbridge: Nvidia Nforce 680i SLI MCP (which is same as prior 590 SLI MCP)
(thus _possibly_ the "nv" SATA driver?)
Ethernet: dual-port something, probably Nvidia. Uncertain.
Sound: "Azalia" High Definition Audio
Firewire: Texas Instruments TSB43AB22A
Video: maybe Nvidia GeForce 7900 GTX, maybe Nvidia 8800 GTX
More about all this below.

Either of these is ridiculously excessive for most needs.

I'm not sure I understand the datasheet about this device correctly:
Seems like it connects to your ethernet network and DHCPs. Then, it
somehow streams out video -- some level of JPEG compression? -- and
there's something about how you can get to that streaming content either
using a Java-equipped Web browser or using something called "IPView
software". Web browsers with either Java or ActiveX can control camera
pan/scan, etc.
So, there you go; seems to just need a Web browser with a JRE plugin.
OK, getting back to that motherboard: The "forcedeth" ethernet driver
will either work or not, video drivers will either work or not, audio
drivers will either work or not, SATA drivers will either work or not,
depending on how bleeding edge your distro's kernel and X11 software
are. Nvidia just, well, really sucks at cooperating with the open
source community, which is one reason why I'd stay far, far away from
its chipset, especially the newest ones at any given time.
But then, if you're a gamer, you're probably an Nvidia fan, and are
going to go there anyway. ;-> And you're going for balls-to-the-wall
performance and maximum framerate, and don't care about stability, power
conservation, noise reduction, I/O robustness (other than video), video
picture quality, or ability to be happy just with genuine open source
drivers.
(I'm not a gamer.)
